Abstract
A device for limiting slip of a torque converter at its high temperature condition performs a slip limiting control by reducing slip rotation between an input element and an output element of the torque converter in a low-load operation region of an engine is carried out, or a lockup control for eliminating the slip rotation. The region of the slip control is expanded to a high-load operation region of the engine, when the temperature of torque converter hydraulic oil is not lower than a predetermined temperature.
Claims16
A slip limiter device for limiting slip of a torque converter in a high temperature condition thereof, by carrying out a slip control for reducing slip rotation between an input element and an output element of said torque converter in a low-load operation region of an engine, or a lockup control for directly coupling said input and output elements to eliminate said slip rotation, wherein said slip control is carried out in a region which is expanded to a high-load operation region of the engine when a torque converter hydraulic oil is at a temperature not lower than a predetermined temperature.
